Online Community of Zenith Builders and Flyers
I thought with Chris Heintz's passing, I would dig out the earliest Zenair brochures I could find, roughly back from the mid to end 1980s.
Those old black and white advert flyers of Chris' are pretty crude but they showed off his range of planes. Some models had a lot of staying power (the 600 and 701), while others weren't around long (the Zipper, Cricket MC12, and Acro Zenith).
[May 4th:] Added 2 more scans, from when Zenair was still in Nobleton.
